SAFETY-PIN.

Specification of Letters Patent- I I Patented Apr. 9, 1918.

Application filed November 24, 1917. Serial No: 203,736.

To all whom it may concern:

Be it known that I, ANTON K. MASSA, a subject of the King of Austria, anda resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Safety-Pin, of which the following is a full, clear, and exact description.

An object of the invention is to provide a simple, inexpensive and eflicient pin which will not become unlockedaccidentally.

Another object of the invention is to provide a spring-actuated catch which will retain the end of the pin and prevent an accidental disengagement of same from the hook on which the catch is provided.

With'the above and other objects in View, the nature of which will more fully appear as the description proceeds, the invention consists in the novel construction, combination and arrangement of parts as herein fully described, illustrated and claimed.

In the accompanying drawings, forming part of the application, similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of a pin embodying my invention;

Fig. 2 is an end elevation of the pin;

Fig. 3 is a perspective view of the catch;

Fig. 4 is a section through the lock on line 44, Fig. 8;

Fig. 5 is a perspective view of the locking p g;

Fig. 6 is a horizontal cross section on line 6-6, Fig. 2;

Fig. 7 is a section similar to that shown in Fig. 4 to show the catch displaced when removing or introducing the end of the pin into the lock; and

Fig. 8 is an enlarged side elevation of the lock and pin engaged therein.

Referring to the drawings, 9 is a pin pivotally connected at one end to a lug 10 rising from a plate 11 which is adapted to carry the ornamental part of the pin. The plate 11 also carries a hook 12 into which the sharp end of the pin is adapted to enter.

A catch 13 is mounted pivotally in the hook to form the snap for same. The catch has a flat surface 14 which rests against the straight side of a spring 15 which is located in a slot 16 provided in the hook. The slot 16 is bridged between the ends near the rear of the hook, as shown at 17. The spring 15 has a recess 18for engaging the bridge 17, whereby said spring is maintained in position in the hook.

- The engagement of the fiat surface 1& with the spring maintains the arm 19 of the catch against the end of the hook, thereby closing the entrance to the hook. The catch has also a shorter arm 20, so to say, formed by the flat surface and the recess. This shorter arm is adaptedto engage the end of thehook and thereby limit the outward movement of the catch. The purpose of this arrangement isto bridge the opening in the hook in case the spring 15 breaks.

To disengage theipin from the lock the same ispressed toward the recess in the catch and outwardlylof the hook. The pressure applied to the longer arm of the catch by this movement displaces the catch on its pivot against the resistance of the spring 15 thereby moving the arm away from the hook and permitting the withdrawal of the pin (see Fig. 7). To introduce the pin into the hook the pin is brought on to the hook and moved against the arm. 19 of the catch. The end of the arm is cut on the bias so as to form a V groove with the curved surface of the hook. In consequence the pin forms a wedge which forces the arm 19 of the catch away from the hook surface against the resistance of the spring and allows the pin to enter the hook (see Fig. 7).

From the above description it will be seen that my lock is a snap hook in which the snap or catch has an outside arm extending beyond the gap in the hook, and which arm is maintained against the hook by a yielding member. This snap has also an inner arm the length of which is such that it will bridge the opening of the hook if the same is moved against the end of the hook. If the spring breaks and the inner arm is free to move it will come in contact with the end of the hook and will bridge the opening, thereby preventing an accidental disengagement of the pin with the hook.

I claim:

1. A safety pin comprising an ornament carrier, a pin foldable to and from the ornament carrier, a hook on the carrier for receiving the end of the pin, a snap pivotally connected to the hook to present an outer arm adapted to be moved against the end of the hook, said hook having a bridged slot, and a spring in said. slot engagmg the slot of the hook, a bridge in said slot of the hook engaging the spring and whereby the spring is retained in the slot, and asnap pivotally connected to the hook so as to engage the spring, said spring normally forcing the end of the snap against the outer face of the end of the hook.

3; A safety pin comprising an ornament carrier, a pin pivotally connected to the carrier, a hook on the carrier for engaging the end; of the pin, a spring-actuated snap in said hook having an outer and an inner arm, the inner armi of said hook being long enough to bridge the opening of the hook, the outer arm being normally in contact With the outer face of the end of the hook.

4:. A safety pin comprising an ornament carrier, a pin pivotally connected thereto, a

' hook on the carrier engaging the end of the pin, a snap pivotally connected to said hook and having an inner and an outer arm, and a spring in said hook for engaglng the snap so that the outer arm is normally maintained against the end of the hook and the cess engaging the bridge and a snap pivotally connected to the hook and presenting an outer and an inner arm and engaging the spring Which normally tends to maintain the arm of the snap against the outer face of the end of the hook, saidonter arn being adapted to be normally maintained in proX- imity of the spring, said outer arm tapering at its end to form a V-shaped groove with the curved surface of the hook whereby the spring may be caused to displace the arm when brought into the groove formed by the arm and the curved surtace ofthe hook.
